Which of the following represents the correct path of electric field lines when a metallic sphere is placed in a uniform electric field?

In a certain region of space,there exists a uniform electric field of value $2 \times 10^2 \hat{k} \ Vm^{-1}$. $A$ rectangular coil of dimension $10 \ cm \times 20 \ cm$ is placed in the $xy$-plane. The electric flux through the coil is......$Vm$.

The spatial distribution of the electric field due to two charges $(A, B)$ is shown in the figure. Which one of the following statements is correct?

Assertion : Electric lines of force never cross each other.
Reason : Electric field at a point superimpose to give one resultant electric field.

The number of electric lines that emerge from a finite charge $+q$ is . . . . . . .

If an electric field is given by $\vec{E} = 10 \hat{i} + 3 \hat{j} + 4 \hat{k}$,calculate the electric flux through a surface of area $A = 10 \text{ units}$ lying in the $yz$-plane.
